##### TimeBase management functions #####
===============================================================================

*** TIM Driver: how to use it in Timing(Time base) Mode ***
===============================================================================
[..] To use the Timer in Timing(Time base) mode, the following steps are
mandatory:
(#) Enable TIM clock using
RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function.
(#) Fill the TIM_TimeBaseInitStruct with the desired parameters.
(#) Call TIM_TimeBaseInit(TIMx, &TIM_TimeBaseInitStruct) to configure
the Time Base unit with the corresponding configuration.
(#) Enable the NVIC if you need to generate the update interrupt.
(#) Enable the corresponding interrupt using the function
TIM_ITConfig(TIMx, TIM_IT_Update).
(#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
[..]
(@) All other functions can be used seperatly to modify, if needed,
a specific feature of the Timer.

===============================================================================
##### Output Compare management functions #####
===============================================================================
*** TIM Driver: how to use it in Output Compare Mode ***
===============================================================================
[..] To use the Timer in Output Compare mode, the following steps are mandatory:
(#) Enable TIM clock using
RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE) function.
(#) Configure the TIM pins by configuring the corresponding GPIO pins
(#) Configure the Time base unit as described in the first part of this
driver, if needed, else the Timer will run with the default
configuration:
(++) Autoreload value = 0xFFFF.
(++) Prescaler value = 0x0000.
(++) Counter mode = Up counting.
(++) Clock Division = TIM_CKD_DIV1.
(#) Fill the TIM_OCInitStruct with the desired parameters including:
(++) The TIM Output Compare mode: TIM_OCMode.
(++) TIM Output State: TIM_OutputState.
(++) TIM Pulse value: TIM_Pulse.
(++) TIM Output Compare Polarity : TIM_OCPolarity.
(#) Call TIM_OCxInit(TIMx, &TIM_OCInitStruct) to configure the desired
channel with the corresponding configuration.
(#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
[..]
(@) All other functions can be used separately to modify, if needed,
a specific feature of the Timer.
(@) In case of PWM mode, this function is mandatory:
TIM_OCxPreloadConfig(TIMx, TIM_OCPreload_ENABLE).
(@) If the corresponding interrupt or DMA request are needed, the user should:
(#@) Enable the NVIC (or the DMA) to use the TIM interrupts (or DMA requests).
(#@) Enable the corresponding interrupt (or DMA request) using the function
TIM_ITConfig(TIMx, TIM_IT_CCx) (or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)).

##### Input Capture management functions #####
===============================================================================

*** TIM Driver: how to use it in Input Capture Mode ***
===============================================================================
[..] To use the Timer in Input Capture mode, the following steps are mandatory:
(#) Enable TIM clock using RCC_APBxPeriphClockCmd(RCC_APBxPeriph_TIMx, ENABLE)
function.
(#) Configure the TIM pins by configuring the corresponding GPIO pins.
(#) Configure the Time base unit as described in the first part of this
driver, if needed, else the Timer will run with the default configuration:
(++) Autoreload value = 0xFFFF.
(++) Prescaler value = 0x0000.
(++) Counter mode = Up counting.
(++) Clock Division = TIM_CKD_DIV1.
(#) Fill the TIM_ICInitStruct with the desired parameters including:
(++) TIM Channel: TIM_Channel.
(++) TIM Input Capture polarity: TIM_ICPolarity.
(++) TIM Input Capture selection: TIM_ICSelection.
(++) TIM Input Capture Prescaler: TIM_ICPrescaler.
(++) TIM Input CApture filter value: TIM_ICFilter.
(#) Call TIM_ICInit(TIMx, &TIM_ICInitStruct) to configure the desired
channel with the corresponding configuration and to measure only
frequency or duty cycle of the input signal,or, Call
TIM_PWMIConfig(TIMx, &TIM_ICInitStruct) to configure the desired
channels with the corresponding configuration and to measure the
frequency and the duty cycle of the input signal.
(#) Enable the NVIC or the DMA to read the measured frequency.
(#) Enable the corresponding interrupt (or DMA request) to read
the Captured value, using the function TIM_ITConfig(TIMx, TIM_IT_CCx)
(or TIM_DMA_Cmd(TIMx, TIM_DMA_CCx)).
(#) Call the TIM_Cmd(ENABLE) function to enable the TIM counter.
(#) Use TIM_GetCapturex(TIMx); to read the captured value.
[..]
(@) All other functions can be used separately to modify, if needed,
a specific feature of the Timer.
